3. The method of claim 1, wherein the transmission power configuration is received from one of: the connected UE or the base station.

10. The method of claim 9, wherein the retransmission acknowledgement status is transmitted via the side-link channel at the first transmission power stepped up according to the power step-up indication.

11. The method of claim 1, further including selecting the first transmission power for the acknowledgement status from among multiple transmission powers including the first transmission power stepped up according to the power step-up indication and further including the second transmission power.

13. The method of claim 12, wherein the UE transmits the acknowledgement status to the connected UE via the side-link channel at the first transmission power stepped up according to the power step-up indication to enable the base station to receive the acknowledgement status while the UE is associated with the unconnected or idle state with respect to the base station, and wherein the UE receives the retransmission of the side-link transmission directly from the base station.

14. The method of claim 1, wherein the UE receives the transmission power configuration from the connected UE via a sidelink control information (SCI) message.
